The document summarizes information about sacroiliac (SI) joint dysfunction and the SImmetry Sacroiliac Joint Fusion System, a minimally invasive surgical treatment. It describes how SI joint pain is a common cause of low back pain, and how the SImmetry system aims to provide relief through fusion of the SI joints without the need for invasive open surgery. It also outlines what patients can expect from the procedure, including small incisions, general anesthesia, a one to two day hospital stay, and a recovery period involving limited weight bearing.

The power to make a difference.
At Zyga, your quality of life is important
to us. That’s why we design minimally
invasive surgical solutions to treat
common—yet underserved—painful
spine conditions. Our goal? To provide
you with the relief you need to return
to the activities you enjoy.

3. The problem is real.
So is the solution.
For years, sacroiliac (SI) joint pain was considered difficult—if
not impossible—to diagnose. What’s more, the only permanent
solution was invasive open SI joint fusion surgery that resulted
in a painful and challenging rehabilitation process and limited
success. That’s why we created the SImmetry®
Sacroiliac Joint
Fusion System (SImmetry).
>> SImmetry
Our minimally invasive surgical solution
is designed for individuals with SI Joint
Dysfunction or Sacroiliitis who haven’t
gotten relief from conservative care,
such as physical therapy, chiropractic
treatment or SI joint injections.
>> Results
Our system helps stabilize your SI
joints—offering you the potential to
return to an active lifestyle and regain
your ability to perform the daily tasks
that keep life moving forward.
SI JOINT DYSFUNCTION

4. Good to know.
Your SI joints connect your spine to your pelvis. They absorb
shock and provide stability for your body. Normally, your SI
joints have very little movement. Yet, inflammation, wear and
tear or a single incident can damage them, changing the normal
movement and creating chronic and often debilitating low back
pain. Common causes of SI Joint Dysfunction are:
>> Injuries
A fall, car accident or simple misstep can
damage your SI joint. Awkward lifting or
twisting can too.
>> Previous lumbar surgery
Fusion of the lumbar spine alters its
natural movement and ability to absorb
shock. Sometimes this “transfers” forces
to the SI joints, resulting in excessive
stress or degeneration.
>> Anatomic variations
Uneven leg length, abnormal gait, and
scoliosis can put additional stress on the
SI joints to maintain stability, which can
cause degeneration and pain.
>> Pregnancy
The ligaments that stabilize the SI joints
stretch to allow for delivery. If they
remain loose post-pregnancy, it may
cause painful movement of the SI joints.
UNDERSTANDING SI JOINT DYSFUNCTION

5. Your SI joints
The SI joints have many nerve endings, so they can
be very painful when degeneration or inflammation
affect their ability to move properly.

6. IS it SI?™
Your doctor can perform simple tests to help determine the
source of your low back problems. Some common symptoms
of SI Joint Dysfunction include:
>> Pain in your buttock
This pain is usually a dull ache on one
side of your lower back and may extend
into the thigh.
>> Pain and discomfort performing
daily activities
These activities may include walking
up and down stairs, climbing hills,
vacuuming and other activities that
require your pelvis to twist.
Difficulty sitting or lying down
This is often experienced as an ache
on one side that causes you to sit on
one buttock to relieve the pain in the
other side.
IS IT SI JOINT DYSFUNCTION?

7. IS SIMMETRY THE NEXT STEP?
Exhausted
conservative therapy?
Have you tried the following conservative care options for
at least six months without relief?
−− Anti-inflammatory medications
−− Chiropractic treatments
−− Pain medications
−− Physical therapy
−− SI joint injections
−− Supports or braces
If so, your doctor may recommend SI joint fusion surgery as
the logical next step.

8. What to expect.
SImmetry may restore your ability to comfortably return to
the activities you enjoy. Commonly asked questions about the
procedure include:
How big is the incision?
The procedure requires two small
incisions, usually only two centimeters
long. They’re made on the side of your
buttock and no muscles or ligaments
are cut, enabling you to return to normal
activity levels more quickly and with less
pain than more invasive procedures.2
Will I be awake?
No. Your surgeon will use general
anesthesia, so you will be unconscious
during the procedure, which typically
takes one hour to perform.3
When can I go home?
Your surgeon will decide the length
of your hospital stay, but most patients
return home after one or two days.2
What will recovery be like?
Although each recovery is different,
some patients experience immediate
relief. Your surgeon will design a recovery
plan to fit your situation. It will often
limit your ability to bear weight for a few
weeks—and will likely involve walking
with crutches—to allow your body time
to heal.
SI JOINT FUSION SURGERY

9. Finally, this new technology gives chronic SI
Joint Dysfunction patients a great surgical option
that allows a true sacroiliac joint fusion. Patient
response and outcomes so far have been very
encouraging.”
